Use Quest 2 As A Display?

Hi All,

Firstly, does Quest 2 allow HDMI input? ie: Using HDMI to Type C with HDMI connected to a Console/PC.

If yes, has anyone worked on an app that essentially allows you to turn your Quest 2 into a home theatre like the Netflix app BUT, you can connect your Xbox or PS5. In the app itself, you adjust the screen size, etc. 

Haven't been able to find something that already exists...
